Loud-speaker combined with a device for producing lighting effects

Abstract

A loud-speaker is combined with a device for producing lighting speakers is covered by two discs provided with openings and, for example, being formed of a grating. The inner disc of the discs, which is facing the speaker cone is rotatable, whereas the outer disc is stationary. Rotation of the rotatable disc is driven either via a motor or via driver members fixed to the speaker cone of the loud-speaker which are actuated by transmission of the vibrations of the speaker cone to the rotating disc in order to provide rotating movement. Light sources for illuminating the surface of the inner or, respectively, outer disc, which is facing the light sources, are provided either within the speaker cone or outside of the loud-speaker. The lighting effects are then generated by the rotation of the inner disc.

What I claim is: 
     
       1. A loud-speaker in combination with a device for producing lighting effects, comprising an inner plate-like element and an outer plate-like element, said inner and outer plate-like elements being mutually arranged in parallel orientation of one relative to the other, said inner and outer plate-like elements having a plurality of openings, said inner and outer plate-like elements having a surface; said loud-speaker having a funnel shaped speaker cone, said inner plate-like element covering said speaker cone, said outer plate-like element covering said inner plate-like element, one of said inner and outer plate-like elements being movable relative to the other; means for moving said one of said inner and outer plate-like elements relative to the other; means for mounting said inner and outer plate-like elements in said parallel orientation of one relative to the other; and at least one light source illuminating said surface of one of said inner and outer plate-like elements. 
     
     
       2. The loud-speaker in combination with a device for producing lighting effects as claimd in claim 1, wherein said inner and outer plate-like elements have a circular circumference, said circular circumference defining a center; at least one of said inner and outer plate-like elements being supported for rotating movement around said center of said circular circumference. 
     
     
       3. The loud-speaker in combination with a device for producing lighting effects as claimed in claim 1, wherein each of said inner and outer plate-like elements comprise a grating. 
     
     
       4. The loud-speaker in combination with a device for producing lighting effects as claimed in claim 1, wherein only said inner plate-like element is movable, and further wherein said outer plate-like element is fixed. 
     
     
       5. The loud-speaker in combination with a device for producing lighting effects as claimed in claim 1, further comprising a housing, wherein said inner plate-like element is provided on its said circular circumference with a flange oriented perpendicularly to its said surface, said flange being movably supported via rollers within said housing. 
     
     
       6. The loud-speaker in combination with a device for producing lighting effects as claimed in claim 5, wherein at least one of said rollers is arranged so that said inner plate-like element performs said rotating movement via a drive means connected to said at least one of said rollers. 
     
     
       7. The loud-speaker in combination with a device for producing lighting effects as claimed in claim 1, wherein said inner plate-like element is movably supported on a bearing means attached to said outer plate-like element. 
     
     
       8. The loud-speaker in combination with a device for producing lighting effects as claimed in claim 2, further comprising at least one driver member fixed on said speaker cone of said loud-speaker, said at least one driver member having a free end frictionally engaging said inner plate-like element. 
     
     
       9. The loud-speaker in combination with a device for producing lighting effects as claimed in claim 8, wherein said at least one driver member comprises a wire bent in the shape of a section of a helix. 
     
     
       10. The loud-speaker in combination with a device for producing lighting effects as claimed in claim 8, wherein said inner plate-like element further comprises a protruding ring which is contacted by said free end of said at least one driver member. 
     
     
       11. The loud-speaker in combination with a device for producing lighting effects as claimed in claim 8, wherein said at least one driver member is connected with said speaker cone by glueing. 
     
     
       12. The loud-speaker in combination with a device for producing lighting effects as claimed in claim 8, wherein said free end of said at least one driver member whch contacts said inner plate-like element is provided with a cap of sound-absorbing material. 
     
     
       13. The loud-speaker in combination with a device for producing lighting effects as claimed in claim 1, wherein said speaker cone has an interior; said light source being arranged within said interior of said speaker cone of said loud speaker, said light source illuminating a surface of said inner plate-like element which is facing said speaker cone. 
     
     
       14. The loud-speaker in combination with a device for producing lighting effects as claimed in claim 13, wherein said speaker cone has an inner side, said inner side of said speaker cone being provided with a light-reflecting coating. 
     
     
       15. The loud-speaker in combination with a device for producing lighting effects as claimed in claim 1, wherein said outer plate-like element has a outer surface, said light source being spaced from said outer surface of said outer plate-like element so as to illuminate said outer surface of said outer plate-like element, and further wherein said inner plate-like element is provided with a light-reflecting coating on a surface thereof which faces said outer plate-like element.
